1. 1. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Johannes Jonsson; Anton Andersson; [2021]
   Keywords : Vibratory driving; sheet pile; Technology and Engineering;

   Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

3. 2. Simulation and experimental study for vibration analysis on rotating machinery

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Mohd Shafiq Sharhan bin Zainal; [2020]
   Keywords : Multi Degree of Freedom MDOF ; Rotating machinery; Single Degree of Freedom SDOF ; Unbalance; Vibration analysis;

   Abstract : This student thesis aims to analyze the unbalance on rotating machinery by simulation and experimental. The machinery flywheel rotation is modelled as a Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) system. The model rotation unbalance is simulated by MATLAB. Then the vibration measurement is taken by experimental. READ MORE

4. 3. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Jennifer Eriksson; [2018]
   Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

   Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE

5. 4. Fluid Structure Interaction Modeling of the Dynamic of a Semi Submerged Buoy

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Shatha Hameed Hajwal; Hamza Zeidan Nasser; [2013]
   Keywords : COMSOL Multiphysics; wave energy converter; Dynamic characteristic; Submerged body; Finite Element method FE ; SDOF; ALE.;

   Abstract : This thesis presents a study of buoy systems for wave’s energy by focusing on the development of a model in which modeling of a wave energy conversation is in operation. Throughout the thesis, the buoyancy and motion of the submerged body has been used to describe the wave-buoy interaction. READ MORE
